  • Our take on the Natural Tourmaline Beads Strands, Round, Black, 4mm

    These are natural black tourmaline beads in a round 4mm cut, sold on a roughly 7.8-inch strand of about 43 to 45 beads with 0.8mm holes. Black tourmaline is a dense, opaque stone that reads as near-black with subtle depth, and it is one of the more affordable natural stones in this size. At 4mm they suit delicate bracelets, spacer work and beaded earrings rather than statement pieces. Compared with glass or dyed agate beads, natural tourmaline varies bead to bead in tone and surface, so expect slight irregularity rather than uniform color.

    Pros

    Cons
    • Black tourmaline is brittle and can chip at the hole
    • Natural strands vary in tone, luster and roundness
    • 4mm is too small for chunky or statement designs

    Questions and answers

    Are these beads really natural tourmaline?
    They are sold as natural black tourmaline, an opaque stone that is near-black in color. Natural strands show slight variation in tone and surface, which is normal for the stone.
    What can I make with 4mm beads?
    Fine bracelets, anklets, beaded earrings and spacer accents in multi-stone designs. The small size keeps pieces light, but it is too small for chunky statement jewelry.
    What stringing material fits the 0.8mm holes?
    Beading wire, thin elastic cord and fine nylon thread up to about 0.8mm. Thicker leather cord or large gauge wire will not pass through.
    How many beads come on a strand?
    About 43 to 45 beads on a strand of roughly 7.8 inches. Counts can vary slightly because each bead is cut from natural stone.
    How does black tourmaline compare with black onyx or obsidian?
    Tourmaline is harder and more brittle than onyx, so it chips more easily at the hole. Onyx and obsidian are more uniform in color and generally tougher for everyday wear.
    Do I need to clean or prepare the beads before use?
    A quick wipe with a soft cloth is enough. Avoid soaking them, and check each hole for rough edges before stringing to reduce chipping.
    Where is the Natural Tourmaline Beads Strands, Round, Black, 4mm cheapest?
    At Amazon, for $3.47, as of our latest check.
